         0.8501030000000001, 3.647296, 1.28503]

Answer 1

just add

.stringValue

to your NSNumber variable

Answer 2

From what you posted is an array of Double if you don't annotate them explicitly. If the array you posted is as it is, then you need this:

let arrayOfDoubles = [68.208983, 6.373902, 1.34085, 3.974012, 110.484001, 61.380001, 1.325202, 0.8501030000000001, 0.8501030000000001, 0.8501030000000001, 3.647296, 1.28503]
let stringArrayOfDoubles = arrayOfDoubles.map { String($0) }

Or, if you explicitly annotate the type as [NSNumber] then you will need this:

let arrayOfNumbers: [NSNumber] = [68.208983, 6.373902, 1.34085, 3.974012, 110.484001, 61.380001, 1.325202, 0.8501030000000001, 0.8501030000000001, 0.8501030000000001, 3.647296, 1.28503]
let stringArrayOfNumbers = arrayOfNumbers.map { $0.stringValue }
